How many kilometers does Jetta clean the nozzle?

Generally, the nozzle can be cleaned once every 2 years or 50,000 to 80,000 kilometers, depending on the gasoline quality in the area where the vehicle is used.

There are two methods for nozzles: one is disassembly-free cleaning, and the other is disassembly-free cleaning.

It is necessary to clean the engine nozzle. Dirty engine nozzle will lead to a series of faults, such as increased fuel consumption, insufficient power and idling jitter. Personally, the biggest impact is the increase in fuel consumption. After all, the current oil price is so expensive, it still hurts a little. It is necessary to clean the injector regularly, and go to a large gas station to refuel. Because the poor quality of gasoline leads to carbon deposition or damage to the nozzle, it is not worth the candle.
